The 1966 Pontiac GTO convertible remains one of the most coveted silhouettes of the original muscle car era, representing a peak in General Motors’ mid-sixties design language. This particular example, refurbished circa 2016, successfully bridges the gap between a pure restoration and a modern pro-touring machine. Finished in a sinister black with a contrasting red pinstripe, it captures the aggressive spirit of the “Goat” while incorporating significant mechanical upgrades that allow it to compete with modern road standards.
Stacked Headlights and a Timeless Profile
The exterior of this GTO is defined by its deep black finish and the iconic stacked headlight arrangement that became a signature of the brand in 1966. A power-operated white convertible top provides a sharp visual contrast, while the integrated hood scoop and chrome-trimmed rocker panels emphasize its performance pedigree. Modern LED lighting has been subtly integrated for improved visibility, and the brightwork on the bumpers and window surrounds has been maintained to a high standard, ensuring the car retains its factory-fresh curb appeal.
Parchment Vinyl and Digital Integration
Inside the cabin, the GTO features a striking Parchment vinyl upholstery that covers the front bucket seats and rear bench, paired with replacement black carpeting. The dashboard retains its vintage charm with woodgrain trim, but has been upgraded with a Dakota Digital instrument cluster that includes a 120-mph speedometer and tachometer. A wood-rimmed steering wheel and a center console featuring a performance shifter provide the tactile feedback expected of a manual muscle car, while an AM radio and factory-style seatbelts maintain a sense of period correctness.
Rebuilt 389ci V8 and Tremec Five-Speed Precision
At the heart of this GTO is a rebuilt 389ci V8 engine enhanced with an Edelbrock intake manifold, Edelbrock cylinder heads, and a Holley 750-cfm carburetor. While the factory output for a standard 389ci was roughly 335 hp (340 PS) and 431 lb-ft (584 Nm) of torque, these modern top-end components likely elevate those figures to a higher performance benchmark. Power is delivered through a Tremec TKO500 five-speed manual transmission and a 12-bolt rear axle, providing a much-improved cruising experience compared to the original four-speed units.

A Competitive Muscle Car Contender
The 1966 GTO occupies a unique space in the market, often compared to the Chevelle SS and Oldsmobile 442. This specific build gains a competitive edge through its suspension and drivetrain upgrades. The inclusion of Viking coilovers and tubular front control arms addresses the handling shortcomings of original A-body cars, while the Tremec swap makes it a viable long-distance cruiser. For collectors, the 389ci V8 remains the “correct” displacement for a 1966 model, providing the right balance of heritage and modern usability.
Modernized Heritage for the Open Road
This 1966 Pontiac GTO convertible is an exceptional marriage of classic Pontiac styling and thoughtful modern upgrades. It offers the visceral thrill of a 1960s muscle car with the added reliability of a five-speed overdrive and an adjustable modern suspension. Whether it is being driven with the top down on a backroad or showcased at a regional meet, this GTO stands as a premier example of why the “Grand Turismo Omologato” nameplate remains a titan of American automotive history.
